Title: Method and device for controlling disconnection of starter of automobile
Inventor: LEFEBVRE BRUNO
IPC: F02N11/08
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent the excessive operation of a starter and the disconnection before suitable starting of an engine caused by fluctuation of the buttery voltage by setting a threshold value to a value according to a value of the power supply voltage in starting of the starting operation. SOLUTION: A control unit 4 continuously measures the voltage of a terminal B during the starting operation. The measured voltage U is compared with a threshold value by a comparator. This threshold value is the final voltage in the completion of the starting operation and is determined according to an initial value of the voltage. If the voltage is lower than this threshold value, blocking of a transistor 3 is prohibited. However, when the voltage is higher than the threshold value, blocking of the transistor 3 is not prohibited, and supply of electric power to a starter D is stopped. Therefore, the time of the starting operation can be shortened to the required minimum length. Moreover, fluctuation of the battery voltage can be restrained.

Abstract: PURPOSE:To increase the accuracy of a treatment plan. CONSTITUTION:A living body is exposed to weak X-rays from an X-ray source and the lesion of the living body is observed by means of fluoroscopy. In this case, not only the lesion but also rectangular blades 27a for planning are observed. The rectangular blades 27a are moved as needed and the outline of the shadow of each rectangular blade 27a is made to coincide with that of the lesion. When the outlines coincide with each other, rays of light are applied to the living body from a light source and then the shadow of each rectangular blade 27a formed by the light is projected on the surface of the living body. Because the shadow formed by the light and projected on the surface of the living body is in a form similar to that of the lesion, an accurate treatment plan for the lesion is made possible by the shadow.
